I got a note about this last night and wanted to pass it along. First Down Laser Systems has been working on a first down marker that could speed up the game.
Instead of an official physically bringing the yardage marker and chain to the middle of the field for measurement, a green laser is emitted from this new marker.
According to the information, it can be accurate up to 1/16th of an inch. It doesn’t take long to set up. In fact, once the laser is accessed, a green line will zoom across the field to the other marker to form the first down line.
